I wish there was a like button here so I could give you a tip of the hat w/o cluttering up the forum with thank you or nice work posts for all the awesome things here but anyway... crusher... thank you for these diagrams and all of your awesome contributions you are probably currently the most active/helpful member here that really makes this forum what it is. Good work.

Thanks guys! I've accepted that I don't have the skills, time, or money to do half the things I would like. But I do have ideas I love this forum, the chance you all provide to be a small part of some really amazing creations, or just helping put a smile back on kids faces when their rides come roaring back to life

I just realized I didn't finish posting diagrams or descriptions here Back to work!

Wow...i have to say thumbs up crusher...thats a great help for guys with no experience like me ...and even tho that i quiet dont understand them all im learning a lot from this..keep up the good work man..!!

This provides 12v to the single rear motor. It will likely hold up well with smaller riders It retains the original kid control and remote control features, as well as lights, mp3, and anything else that came on it originally.

I have a 12v version of the Chinese (Lambo Aventador) that I would love to speed up. I'd prefer not to re build it completely at this time, is there something similar with the 12v version as the last diagram for the 6 volt version? Give it more speed, but keep control and sound?Thanks.!

Thanks, I just need to add 2 relays (I have a bunch from my old Car audio system) and a fuse for the new battery and He will be cruising faster? The 12v one I have has two motors, do I split the outputs from the relays or do I need to add 2 relays per motor? Thanks!

Hey toycrusher is there any revised wiring diagrams for a 18v set up using 3 X 6v batteries,using a 6v (mostly likely a 6amp)charger? I did read another post regarding this type of set up,just wondering if that diagram still is the best one. Involved 3 relays.Cheers

Nothing new on that front. Members have done it with switches, relays, and my favorite, a 7 way trailer plug

Been trying to figure out something on this diagram. What's the device with the two bolts on the right side underneath the top 6V battery?

That's a resettable circuit breaker. You could put a fuse there instead

Hi. I'm new to this and I think I have already fried my first board. I have the avigo BMW X5 (http://www.rollplay.net/products/view/6v-bmw-x5). I added 3 x 12v 7ah batteries in parallel each with a fuse on the positive wire (5 in total including the wires connecting the batteries), another 6v motor which I have added using a 2 to 1 adapter I made. Which goes into the stock pc board. All was well until today when it stopped. Lights work, radio but when accelerator is pressed motors just click.

Any chance you could let me know how to wire it without damaging the new board that's on the way? But keep the two motors and batteries? My kids were loving the power ...

Thanks so much for getting back to me. I have created a wiring diagram of my current setup. Like I said before i'm pretty sure it's fried (testing everything with the voltage meter tomorrow) but considering i only have mp3 player and remote steering still working unlikely it could be much else. Thanks for directing me to your diagram but I'm a complete noob and struggled to follow it in regards to my setup. Do you think you could scribble on the image and show me what i need to add to stop me from frying another circuit board please? Also do you know of any 12v circuit boards from another model that I could use instead where I could plug everything into, retain all of the current features but leave me with no risk of frying it?

Your almost there. Replace your 12v batteries with a single 6v. The wires that currently go to your motors need to go instead to the green and blue wires in my diagram that read "connect to original motor leads". Wire up the rest with relays as shown and your good to go

Ok so a further update. Went over the car with a volt meter and turns out i have blowen the relays on the pc board. I was pumping 21+ amps though the relays that could only take 10 amps. So i'm going to get a fresh board and replace these relays that are currently on the board http://www.futureelectronics.com/en/tec ... 2-1ZST(257).aspx?IM=0

Those batteries would take the place of the second 6v in the diagram giving you 18v power! The 6v is necessary for the board to survive, the relays handle all the current giving power to your motors but protecting the circuit board.

Would it be possible if someone could take a picture of a car that has this set up? I'm not entirely sure what some of the wires coming out of the relays look like. Sorry...still a newbie at all this but I'm trying really hard to learn all this.Edit: I watched this video

and it helped me get a better understanding of relays and what it looks like. The diagram looks different as there is 2 relays and 3 batteries involved, so if anyone still has a picture i would greatly appreciate it!!!!!

Tutu, the relays are something that you are providing. To utilize the existing gas pedal and shifter. The relays are activated by the shifter. Unless someone found the exact same car that you have, the wires are different.

Oh okay. I had the impression that they were in the car already. Thank you! once again, sorry for all the questions suburbancharlie. You have been a great help. Expect more questions to come though! :D:D

It's kinda small or tiny print, but the relays are"fed" by the original motor wires. I dunno if you can print just that image, but it should be a bit bigger, and definitely would be handy to have the ability to glance up at it taped to the wall, while working on it!

Don't thank me, thanks all go to toycrusher!

And no worries, we all learn at some point. And those that don't, we'll I try to avoid them =0

You take the original motor wires, and they act as a "controller" for the relays that you are adding.

The relays will control the voltage that the original equipment CAN NOT HANDLE. The stock design will typically fry when you double the voltage to the sensitive circuit boards.

The motors tend to be far more tolerant of the over voltage, matter of fact, there are even some members running 24 volts without issue, to even some of the 6 volt motors. Personally I've been maxing at 18 volt, but not much of what I own is from this decade. Old worn motors don't take kindly to an adult and 24V, ask my sister in law, that burn up smoke stunk like holy heck and lingered!

@toycrusher ..need some help please. I'm not an elec buff, but your diagram is quite simple to understand.As far as what I can tell, I connected the everything as per your diagram.After connecting everything up .. the RC still works .. wheels turn left/right, but the motor is not working .. when i press forward/reverse .. all I hear is this clicking sound ..the same effect when the pedal is pressed.

After this I can up last night .. will try and determinate the location of the fault.

Any suggestions on what it could be?

Thanks

The low current side is working, the relays are switching. It's the high current side that's missing a link
